LAWRENCE T. TUCKER, OF POLLOCK, MISSOURI.

HOISTING APPARATUS.

Application filed April 20, 1921.

To all whom may concern:

Be it known that I, Lawnnnon T. TUCKER, a citizen of the United States,residing at Pollock, in the county of Sullivan and State of Missouri,have invented certain new and useful Improvements in Hoisting Apparatus.of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to a hoisting apparatus and the object of theinvention is the construction. of a comparatively simple and eflicientapparatus, involving an efficient frame for lifting or hoisting a loadof any kind.

Another object of the invention is the construction of a peculiar frameof a hoisting apparatus which. is very strong and durable, yet.relatively simple in construction.

With these and other objects in view, my invention. comprises certainnovel combinations, constructions and arrangements of parts as will behereinafter described, illustrated in the accompanying drawings, andmore particularly pointed out in the appended claim.

In the drawings:

Figure 1 a perspective view of an. apparatus constructed in accordancewith the present invention.

Figure 2 is a rear view of the apparatus.

Referring to the drawings by numerals, l.-1 are the horizontal basebeams arranged in a Vshaped form, and the front ends of the beams 1 arenotched, on. their under face, at 2, and in these notches is placed ahorizontal front cross piece 3, which cross piece is secured to thebeams 1. Rollers or casters 4; are attached to the under face of thecross piece 3. At the rear end of the beams 1 is secured a rear crosspiece 5, and to the under face of said cross piece 5 is secured a pairof rollers or casters 6. These casters 4- and 6 support the apparatusupon the ground or floor and facilitate the moving of the same, at thewill of the operator. Rear, parallel stands 7 are secured, at 8, to therear ends of beams 1, and near the center of beams 1 and fastened at 9,are attached inclined, front standards 10. A horizontal, top beam 11 issecured between the rear Specification of Letters Patent.

standards '7 and the front standards 10. Behind the front standards 10,and fastened to the top of the beams 1, is a small cross piece 12; thecross piece bears against the rear edges of the front standards 10. A.block 13 is secured between. the rear standards 7, against the loweredge of top beam 11; an inclined brace 14 is fastened at its lower endto the top of cross piece 12, and bears, at its upper end, against thelower face of top beam 11 and against the front face of block 18,efficiently bracing and strengthening the entire frame-structure.

A pulley device 15 is fastened to the front end of beam 11 and anotherpulley device 16 is fastened to its rear end. A drum 17 is attached tothe rear of the standards 7. A shaft 18 is geared to the drum 17 and bymeans of handle 19, the shaft and drum can be rotated for winding thehoisting cable 20 on the drum 1'? or unwinding the same at the will ofthe operator. The cable 20 is threaded through the pulley devices 15 and16, and the outer end of the cable is pro vided with a hook 21 forattaching the hoisting cable to the object or load to be lifted, orlowered.

It is to be understood that my hoisting apparatus can be easily conveyedover the floor or surface to the object or load to be handled and then,by the simple manipulation of the hoisting means, the load can belifted, or lowered, as desired.

While I have described. the preferred embodiment of my invention, andhave illustrated the same in the accompanying drawings, certain minorchanges or alterations may appear to one skilled in the art to whichthis invention relates, and I, therefore, reserve the right to make suchalterations or changes as shall fairly fall within the scope of theappended claim.

What I claim is:

In. a hoisting apparatus, the combination of a pair of horizontal basebeams, a pair of spaced, parallel, rear standards secured to said basebeams, a pair of inclined front standards secured to said base beamsnear their center, a horizontal top beam secured between the upper endsof all of said standards, a block secured against the under face of saidtop beam and between said rear standards, a horizontal cross piecesecured to the top of: said base beams againstthe, rear edges of thefront standards, an inclined brace secured at its lower end upon the top01? said cross piece andsecured against the under face of the top beaminengagement with the front face of said block, and hoisting means carriedby the rearstandards and 10 by the top beam, substantially as shown anddescribed.

In testimony whereof I hereunto aflix my signature. v
